Worked on aemdemos/aps-aemy to deliver a comprehensive UI refresh focused on maintainability and responsive design. Overhauled the header and global navigation, restructuring HTML and CSS while updating JavaScript to enhance mobile navigation, search, and sign-in functionality. Improved the footer by adding contact details, social links, and app store connections, ensuring consistent branding and usability across devices. Emphasized code quality by applying extensive lint fixes and refining styling, which reduced potential regressions and improved maintainability. Leveraged front end development skills in HTML, CSS, and JavaScript to create a more cohesive user experience and lay groundwork for future feature development.
